Behringer kareoke speaker quit after being plugged into my androud ph

Please help me

I plugged my phone into my step dads kareoke. It worked great. He has a lot of equipment that I didnt know how to mess with so i disconnected just the behringer speaker from all else in order to listen to music from my phone. Now it doesnt work. I used a convertor to fit phone jack. Please God say i didnt ruin this.
